Question

• In JAVA: Define a test suite method, define a test method testcube that exercises Calculation.cube() in Calculation class, and Organize your tests in your test suite (testfindMax & testcube)

Given the following code below: 6. 7. 1. public class Calculation { 2. //method that returns cube of the given number 3. public int findMax(int ac[]}{ 4. int max=0; 5. for(int į=1;i<acr.length;i++){ if(max<arc[i]). max=acc[i]; } 8. return max: 10. } 11. //method that returns cube of the given number 12. public static int cube(int n){ 13. return n*n*n; 14. 15. } } 9. }

Answer 1

Java code for above problem

class Calculation
{
   public int findMax(int arr[])
   {
       int max=0;
       for(int i=1;i<arr.length;i++)
       {
           if(max<arr[i])
           {
               max=arr[i];
           }
              
       }
       return max;
   }
   public static int cube(int n)
   {
       return n*n*n;
   }
}
class Main
{
   // test suite method
   public static void main(String args[])
   {
       System.out.println(Calculation.cube(3));   // prints 27
      
       int [] arr=new int[]{1,2,3,4,5};
       Calculation obj=new Calculation();
       System.out.println(obj.findMax(arr));       // prints 5
   }
}
